conclusions our study revealed weak correlation between pe/e-vc and cormack-lehane grade, with 87% sensitivity and 30% specificity. therefore, we concluded that sonographic measurement criteria are not accurate in airway evaluations before anesthesia. results it was observed that correlations between the pre-epiglottic space (pe) and cormack-lehane grades i, ii, and iii were weak. correlations ...

OBJECTIVES/HYPOTHESIS To determine whether Mallampati class correlates with Cormack-Lehane grade in obese adults, and investigate a novel airway trajectory measurement (ATM) to anticipate difficult laryngoscopy. STUDY DESIGN Retrospective cohort plus a pilot study. METHODS One hundred eighty-four nonobese and 160 obese adults underwent laryngoscopy. Spearman correlations, gamma coefficients...

In the course of developing tools for the 2015 Total Recal Track, Track Co-Coordinators Gordon V. Cormack and Maura R. Grossman created an autonomous continuous active learning (“CAL”) system, which was provided to participants as the baseline model implementation (“BMI”) [http://plg.uwaterloo.ca/∼gvcormac/trecvm/]. BMI employs the technology-assisted review (“TAR”) approach described by Cormac...

BACKGROUND Direct laryngoscopy with the Miller laryngoscope (Mil) for infant tracheal intubation is often difficult to use even for skilled professionals. We performed a simulation trial evaluating the utility of a tracheal tube introducer (gum-elastic bougie (GEB)) in a simulated, difficult infant airway model. METHODS Fifteen anesthesiologists performed tracheal intubation on an infant mani...

BACKGROUND Unpredicted Difficult Tracheal Intubation (DTI) with Macintosh occurs frequently in obese patients. We investigated the incidence of DTI using an algorithm based on preoperative assessment with the El-Ganzouri Risk Index (EGRI) and Glidescope® routine use. METHODS We prospectively enrolled morbidly obese patients undergoing abdominal surgery. Patients were scheduled for Glidescope®...

Background and Objective. The Airtraq laryngoscope (Prodol Meditec, Vizcaya, Spain) is a novel tracheal intubation device. Studies, performed until now, have compared the Airtraq with the Macintosh laryngoscope, concluding that it reduces the intubation times and increase the success rate at first intubation attempt, decreasing the Cormack-Lehane score. The aim of the study was to evaluate if, ...

BACKGROUND The efficacy of devices for difficult intubation in paediatric patients, especially with a Cormack-Lehane grade 4 view, has yet to be established. We compared intubating parameters among three devices (the Airtraq®, McGrath®, and Macintosh laryngoscopes). METHODS This study is a randomised cross-over trial. Participants were 20 anaesthetists. Each device was tested three times usin...
